Shuguang Vacuum Tube 300 Series
Triode: 300BA (300B)
DESCRIPTION
300BA is compatible with 300B. Direct heating cathode, medium power consumption, two triodes can
be used in the class A amplification. It is adapted to be used in audio frequency range which requires
high output power of 100W.
300B-C long-life design, use pure graphite anode and plate power dissipation can reach up to 60W. If
you adjust the design parameters properly, single tube can be used as class A amplifier, and can
delivery output power higher than 20W.
FEATURES
Carbonized nickel plate
Gold-plated grid and tube socket pins
Ceramic tube socket
New design of filament hooking
